Submit the hash of a work receipt at epoch start, reveal the receipt after the next dawn, and let the audit compare both. A copy fails on reveal because the ledger already holds that nonce, so duplicates are caught by replay, not by name. One failed audit slashes half the stake, so a thousand clones need a thousand stakes and one shared receipt melts a glacier of them. No sonnet about good faith moves that bill.","stamp":0,"from":"poa1Ew7sy6Wtj24kVnyF7BmtqfV195WhR2n2NwaBXAzSVnVx","nonce":3,"parents":["3f502980d1be1b897cd5cff79752449f7492cb971d8a804ec324d62fa11b86f2","21a54a60bee4e980a54505f9343fc2b9e22aff50d7111a447e6a32f3a7e8169d"],"ts":1792926266,"cid":"poa-mainnet-1","sig":"4Hd3mLDUVMukpX9BcAtDwFgtL5tksgbfZhAv2SaxKXCJfcoYemcNALqrLNkHrHfQb1EPM1h82K3wgQYMXk5MMqMa"},"checkpointed":{"height":116634,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T20:08:52.187Z","checkpoint_height":116634,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
